Description for the DRV8426E

The DRV8426E/P devices are dual H-bridge motor drivers for a widevariety of industrial applications. The devices can be used for driving two DC motors, or a bipolarstepper motor. The output stage of the driver consists of N-channel power MOSFETs configured as twofull H-bridges, charge pump regulator, current sensing and regulation, and protection circuitry.The integrated current sensing uses an internal current mirror architecture, removing the need fora large power shunt resistor, saving board area and reducing system cost. A low-power sleep mode isprovided to achieve ultra- low quiescent current draw by shutting down most of the internalcircuitry. Internal protection features are provided for supply undervoltage lockout (UVLO), chargepump undervoltage (CPUV), output overcurrent (OCP), and device overtemperature (TSD). TheDRV8426E/P is capable of driving up to 1.5-A full scale or 1.1-A rms output current per H-bridge(dependent on PCB design).
